Animals struggle to survive in the bitter winters of the Atlantic.

Winter draws to a close; the Atlantic returns to life.

Summer means plentiful food, and you animals must feed, grow and prepare to start life alone; puffins take a massive leap of faith as they jump from their cliff-top nests into the ocean, 600 feet below.

In the Atlantic's far north, autumn is the season of gales, cooling temperatures and driving rain; this is the season when the wildlife must make the final preparations for winter or migrate to warmer climes.
